Buerger, Marcel;Ehrhardt, Nadine;Barber, Thomas;Ball, Liam T.;Namyslo, Jan C.;Jones, Peter G.;Werz, Daniel B. research published 《 Phosphine-Catalyzed Aryne Oligomerization: Direct Access to α,ω-Bisfunctionalized Oligo(ortho-arylenes)》, the research content is summarized as follows. A phosphine-catalyzed oligomerization of arynes using selenocyanates was developed. The use of JohnPhos as a bulky phosphine is the key to accessing α,ω-bisfunctionalized oligo(ortho-arylenes) with RSe as substituent at one terminus and CN as substituent at the other. The in situ formation of R3PSeR’ cations, serving as sterically encumbered electrophiles, hinders the immediate reaction that affords the 1,2-bisfunctionalization product and instead opens a competitive pathway leading to oligomerization. Various optimized conditions for the predominant formation of dimers, but also for higher oligomers such as trimers and tetramers, were developed. Depending on the electronic properties of the electrophilic reaction partner, even compounds up to octamers were isolated. Optimization experiments revealed that a properly tuned phosphine as catalyst is of crucial importance. Mechanistic studies demonstrated that the cascade starts with the attack of cyanide; aryne insertion into n-mers leading to (n+1)-mers was ruled out.
Recommanded Product: (2-Bromophenyl)boronic acid, 2-Bromophenylboronic Acid is used as an inhibitor of the hormone sensitive lipase.
2-Bromophenylboronic acid, also known as 2-Bromophenylboronic acid, is a useful research compound. Its molecular formula is C6H6BBrO2 and its molecular weight is 200.83 g/mol. The purity is usually 95%.
2-Bromophenylboronic acid is a glucose monitoring agent that has a ruthenium complex with an acidic environment. The nitro group and the amines are in close proximity to the boron center, and this proximity leads to a high nucleophilic character of the molecule. This reactivity allows 2-bromophenylboronic acid to be used as a fluorescence probe for acidic environments. 2-Bromophenylboronic acid also inhibits secretase enzymes, which are involved in Alzheimer’s disease and other neurodegenerative disorders. It is an inhibitor of γ-secretase, which is responsible for cleaving the amyloid precursor protein (APP), and it has shown efficacy against biphenyl, an anticancer drug that binds to benzodiazepine receptors. 2-Bromophenylboronic acid is also an enantiopure compound because all four substituents are different from each other., 244205-40-1.
